I have a Carter, not a Holley?

my idea is carters are very good. i have done tons of them. WCFBS, AFBs, and 2 bbl, and 1 bbls. most of the 2-1 bbls have two screws that go from the top casting into the bottom casting, do NOT over tighten them. . else the casting will warp. . the 2 bbl float level is 1/4 " the AFB run good at 5/16" and the AFB float level is set with the lid upside down so a higher number is a lower level. on AFBs do NOT change the jet AND rod at the same time. you cant know what the change is. change the jet first when that is close then change the rods. on jets change a .060 by .001 is lots less than a .090 changed by .001.
